Spotify Mobile has been out for roughly two weeks now, it’s still in the top ten of the most downloaded free apps in the Swedish app store – currently at number four to be precise. The app has been rated as many times as 1806 at the time of this writing. Quite remarkable.

Spotify Mobile really hit the media (and social sphere) when the story was published. I don’t think there’s a single medium where the story haven’t been posted/dugg/liked/whatever. It spread like a bushfire in a summer breeze throughout Twitter and Digg – they really got everyone excited. Including me.

Don’t get me wrong, I’m not trying to build up some “but”-action here; I love Spotify, and I love the app. I have to say though, that what’s really interesting in all of this is to monitor search patterns on both mobile and premium. Premium being Spotify’s (paid) member service which offers no ads, higher sound quality, unlimited travel access, and exclusive access to pre-releases. So why is this interesting? For one, Premium is of course required in order for you to use Spotify Mobile. The second reason is a killer; search volume index for Spotify Premium is actually greater than the volume for Spotify Mobile:

Not only was it greater during the actual release (when the bushfire spread); it spiked higher, it lasted longer, and it has maintained on a higher level. Of course, as the disclaimer indicates “several approximations are used when computing these results”. Still a good indication of what’s happening.
